Map points using a private transformation function


The IntraMap class provides a specialised form of Mapping which encapsulates a privately-defined coordinate transformation other AST Mapping. This allows you to create Mappings that perform any conceivable coordinate transformation.

However, an IntraMap is intended for use within a single program or a private suite of software, where all programs have access to the same coordinate transformation functions (i.e. can be linked against them). IntraMaps should not normally be stored in datasets which may be exported for processing by other software, since that software will not have the necessary transformation functions available, resulting in an error.

You must register any coordinate transformation functions to be used using astIntraReg before creating an IntraMap.

The IntraMap class inherits from the Mapping class.


In addition to those attributes common to all Mappings, every IntraMap also has the following attributes:


The IntraMap class does not define any new functions beyond those which are applicable to all Mappings.
